A comprehensive study of the response of the ionosphere-plasmasphere system at mid-latitudes to weak (Dstmin > -50 nT) magnetic storms is presented. For the first time, it is shown that weak magnetic disturbances can lead to significant modulation of

This study investigates the causes of nighttime enhancements in ionospheric density that are observed in winter by the incoherent scatter radar at Kharkiv, Ukraine. Calculations with a comprehensive physical model reveal that large downward ion fluxe

The analysis of clutters generated by the reflections from aircrafts at distances up to 400 km and received by the side lobes of the antenna pattern of 100-meter two-mirror antenna of the incoherent scatter radar is carried out. The conditions under
